COMPRESSION-ROLLER FOR WlRE-WARPING MACH INESf SPECIIE'ICATION forming part of Letters Patent NO. 352,138, dated November 9, 1886. Application filed August 23, 1886. Serial No. 211,609. (No model.)

To aZZ whom it may concern:

Be it known that I, ORANGE S. LEE, of

Clinton, in the county of Worcester, State of Massachusetts, have invented a certain new and useful Improvement in Compression-Rollers for Wire WVarping Machines, of which the following is a description sufficient-1y full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the sam'e,-reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is an elevation representing the warp-beam with the roller in position for use, the flare of the groovesin the beam being distorted, or their walls abnormally inclined, in order to better illustrate the principle of the invention; Fig. 2, an end elevation of the roller detached; Fig. 3, a front elevation of the same, and Fig. 4 a vertical transverse section. I

Like letters of reference indicate correspon ding parts in the different figures of the drawings.

It is well knownthat in the mechanism employed in the manufacture of wirecloth the beams of the warping-machines are usually grooved peripherally, or provided at regular intervals with annular flanges, which divide the surface of the beam into corresponding annular grooves, in which the wire is deposited as the beam is filled. In order to fill these grooves properly,a compressor is employed, which bears upon the wire as it is delivered to thebeam, thereby compacting and evening the layers. This compressor usually consists of a roller, which is journaled horizontally in such a manner as to bear upon the layers of wire as they are formed in the groove, and when one groove is filled is moved to the next succeeding groove, and so on throughout the series; but as the grooves are sometimes constructed slightly narrower at the bottom than at the top, or one or both'of their sides wear away by the action of the wire, thereby causing them to incline or the grooves to flare as they. approach the periphery of the beam, a roller which fits the bottom of the groove will not be quite long enough to fit it when the groove is nearly filled with wire, and hence the wire, if very small or when comparatively fine, will tend to pile up at the ends of the roller, or, between the roller and the adjoining flanges, and produce bad work, the layers, more especially the outer ones, not being formed in parallelism with the axis of the beam or properly evened and compressed.

My invention is designed to obviate this difficulty, and t'o that end I make use of an expansible or compensating compressor-roller, the construction and operation of which will be readily understood by all conversant with such matters from the following explanation.

In the drawings,A represents a portion of the frame-work in which the warp-beam is mounted; B, the beam, and C the roller.

The surface of the beam is divided by a series of annular flanges, 00, which are of slightly greater diameterin cross-section at their bases than at their peripheries,into a corresponding seriesof annular grooves,m,or grooves which are of slightly less diameter at the bottom than at the top.

Disposed in front of the bearmand nearly on a plane with its upper side, there is a horizontally-arranged rod, D, on which the sleeve E is fitted to slide. Said sleeve is provided with a pair of arms, b b, which project over the beam B, in the outer or free ends of which the 'roller C is horizontallyjournaled on the trun- 8o nionsf. v

The roller is constructed in two sections or halves, d d, each section being provided cen trally on its outer face ,with a trunnion, f, and on its inner face with an annular groove, 2, and the two sections are connected by the bolt is and nut Z, the bolt being inserted in holes which pass longitudinally through the trunnions, as best seen in. Fig. 4, the holes being slightly larger than the bolt, thus permittingthe sections to slide freely thereon.

A coiled spring, N, is disposed in the grooves 2 within the roller, said spring acting expansively to force the sections (Z d apart, butbeing sufficiently flexible to permit the roller to be readily compressed laterally.

The inner faces of the sections (1, between the grooves z and their peripheries, are murally' serrated, as shown at o in Fig.3, the

teeth of each section fitting loosely in the :00

spaces between the teeth of the opposite section, the object of the serrations being to interloek the sections in such a manner as to cause them to revolve in unison, and at the same time not materially change thebearing or working surface of the roller.

In the use of my improvement the nutl is first so adjusted on the bolt k that when the roller is fully expanded it will fill the groove at the surface of the beam. The roller is then dropped into the groove on at the end of the beam, its weight causing the spring N to be compressed as the sections (I slide down the inclined sides of the flanges :1: until it rests on the bottom of the groove. The wire is then wound onto the beam in the groove, and as th e.

roller rises with each succeeding layer it is expanded by the spring N, thereby keeping it in constant contact with the adjoining flanges, and preventing the wire from overriding and piling up between the ends of the roller and the flanges in a manner that will be obvious to all conversant with such matters without a more explicit description.

Having thus described my invention, what I claim is- 1. A compression-roller consisting of the sections (1, provided with the trnnnions f and the interlocking serrations c, the spring N,in terposed between said sections, and the boltk, extending through said trunnions and provided on opposite ends with a head and aunt, respectively, substantially as described.

2. A compression-roller consisting of the sections (1, provided with the trunnions f, the interior grooves,z,surrounding said trunnions, and the interlocking serrations c, the spring N, 5 interposed between said sections, its ends resting within said grooves z, and the bolt k, extending through said trunnions and provided on opposite ends with a head and a nut, respectively, substantially as described.

3. The expansible roller 0, provided with end trnnnions, in combination with the rod D and the sleeve E, sliding thereon, and having arms I), provided with eyes,w;ithin which said trunnions are journaled, substantially as do 5 scribed.
